Overview

Frequency analysis reveals bright variations in 121 intermediate polars, indicating white dwarf rotation effects.

Key Points

  • Bright variations in about half of the studied intermediate polars indicate white dwarf rotation.
  • Frequency analysis of TESS light curves led to precise measurements of periods in 121 systems.
  • A wealth of brightness changes, including orbital periods and quasiperiodic oscillations, was documented.
  • Observations highlighted the relationship between white dwarf spin signals and power spectrum features.
